Abstract: The disclosure belongs to the technical field of precision test and measurement, and provides a two-dimensional photoelectric autocollimation method and device based on wavefront measurement and correction. According to the disclosure, a link of wavefront measurement and correction of a reference light path is added to a traditional autocollimator measuring method. By using wavefront distortion information of the reference light path in the instrument and driving a deformable mirror to compensate for phase distortion of a beam, the link realizes measurement and control on aberration of the optical system of the autocollimator and improves the imaging quality and spot positioning accuracy of the optical system, thereby improving the angle measurement accuracy of the autocollimator.

Abstract: A centrifugal fan is disclosed. The centrifugal fan includes a housing, and the housing is configured to accommodate an impeller. The impeller rotates relative to the housing. A flow channel that cooperates with the impeller is disposed in the housing. The flow channel includes a pressurization area. In the pressurization area, a static pressure and a flow velocity of an air flow are gradually increased along a rotation direction of the impeller. However, an air inlet is disposed on the housing, and there is a specific gap between the impeller and the air inlet. As a result, when air flows through the pressurization area, there is a specific amount of leakage through the gap. Therefore, an air baffle ring is disposed in the centrifugal fan provided in this application.
